* SSB 2023 relative to SSB 2022.
** Advice value for 2022 relative to TAC and advice value for 2021 (885 600 tonnes).
^ Since SSB in 2022 is between Bpa = 460 000 tonnes and 2 × Bpa = 920 000 tonnes, F = 0.40 is used in the 3-year prediction, giving catches of 504 244, 528 049 and 557 768 tonnes in 2022, 2023, and 2024, respectively. The average of this is 530 020 tonnes. According to the harvest control rule (HCR), the maximum decrease in TAC is limited by 20%, giving a catch of 708 480 tonnes, which corresponds to an F of 0.62 in 2022.
